Try using horizontal orientation in your RadioGroup like below:

(尝试在RadioGroup使用horizontal方向，如下所示：)

<RadioGroup
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:background="#C8E585"
    app:layout_constraintTop_toTopOf="parent" >

    <RadioButton
        android:id="@+id/btn1"
        android:textSize="18sp"
        android:layout_margin="10dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="ColdFusion" />

    <RadioButton
        android:id="@+id/btn2"
        android:textSize="18sp"
        android:layout_margin="10dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Flex" />

    <RadioButton
        android:id="@+id/btn3"
        android:textSize="18sp"
        android:layout_margin="10dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Flash" />
</RadioGroup>
